Covington's "Practical Amateur Astronomy 2 Volume Set" is for beginner and intermediate amatuer astronomers who have or are thinking of aquiring a computerized telescope. It consists of two titles, "How to Use a Computerized Telescope" and "Celestial Objects for Modern Telescopes", which complemet each other well.
The first book, "How to Use a Computerized Telescope" , is divided into two sections. The first covers basic topics on the use, care and feeding of telescopes in general. The second looks at three classic "Go To" telescope families. If you are looking to buy a computerized telescope, or already own one and want to get more out of it, then this is a good place to start.
PART I - Telescopes in general
1. Welcome to amatuer astronomy
2. How the sky moves
3. How telescopes track the stars
4. Using equatorial mounts and wedges
5. Telescope optics
6. Eyepieces and optical accessories
PART II - Three classic telescopes
9. Three that led the revolution
10. Meade LX200
11. Celestron NexStar 5 and 8
12. Meade Autostar (ETX and LX90)
Though the models described in detail in the book are no longer the latest models, the foundations will allow one to get a better understanding of how computerized telescopes work, and how to get more out of their use.
In the second volume, "Celestial Objects for Modern Telescopes", Covington suggests various targets and observing programs. But that is not all. Also are tips on how to get the most out of various sources to identify the object of interest from various catalogs or atlases and to be able to tell a "Go To" telescope how to point to it. Probably the most useful pages in the book are the Bayer/Flamsteed to SAO cross-index and the GVCS constellation codes and star numbers.
PART I - Amatuer astronomy
1. Using this book effectively
2. Observing sites and conditions
3. The Moon, the Sun, and eclipses
4. The planets
5. Comets, asteroids (minor planets), and artificial satellites
7. Stars - identification, nomenclature, and maps
8. Stars - physical properties
9. Double and multiple stars
10. Variable stars
11. Clusters, nebulae, and galaxies
PART II - 200 interesting stars and deep-sky objects
12. How these objects were chosen
13. The January-February sky (R.A. 6h-10h)
14. The March-April sky (R.A. 10h-14h)
15. The May-June sky (R.A. 14h-18h)
16. The July-August sky (R.A. 18h-22h)
17. The September-October sky (R.A. 22h-2h)
18. The November-December sky (R.A. 2h-6h)
A. Converting decimal minutes to seconds
B. Precession from 1950 to 2000
C. Julian date, 2001-2015
The logical follow up for "How to Use a Computerized Telescope", this volume shows one how to use the various sources available to find the objects one is interested in studying. If I had this book when I first bought my LX200, I would have developed better habits in planning my observing sessions by being able to identify objects in the manner that the telescope has them identified in its database to find them quicker to allow more time for study and or imaging.
